This year's fall TV season hasn't even started yet, but CBS is already getting a head start on next year's line-up. The network just ordered its first pilot for the 2013-14 season, a single-camera sitcom called 'Ex-Men' from 'How I Met Your Mother' producer Rob Greenberg.

Sorry to disappoint, but this new series has nothing to do with our favorite band of superheroes. The show centers around a young man who moves into a short-term rental complex and learns life lessons from the older, more experienced men who already live there.

'Ex-Men' will be written and directed by Greenberg, with 'Two and a Half Men' vets Eric and Kim Tannenbaum serving as executive producers.

Getting such an early order for a pilot is a bit unusual, but perhaps CBS wanted to lock up Greenberg since 'How I Met Your Mother' co-creator Craig Thomas has hinted that the show's upcoming eighth season could be its last.

"When we were launching the show, we always thought eight seasons would be great for what we were trying to do," Thomas said. "But we just came off our best ratings year. We still think we have great stories to tell. I don’t know. It’s hard to say good-bye."
